              All Survey Responses for Able Glass Company
              Q: What are some of the most popular brands that Diamond Certified window companies use when working with Los Altos residents?
              A: Diamond Certified window companies use top-quality brands like Marvin, Atrium, Ply Gem, Kolbe and Weather Shield.
              Q: What types of replacement windows do window companies offer?
              A: Window companies offer energy-efficient windows such as double-glazed or triple-glazed windows, low-E (low-emissivity) windows, and gas-filled window units. Double and triple-glazed windows have two or three layers of glass with a vacuum or gas-filled space in between to reduce heat transfer. Low-E windows have a special coating that reflects infrared light, keeping heat inside the home during winter and outside during summer. Gas-filled window units are filled with inert gases like argon or krypton between the panes, which are better insulators than air and can further reduce heat transfer.
